(see p. 7, No. 24; p. 9, No. 25)
This header accommodates several system front panel functions.
Connect the power switch, reset switch and system status indicator on the chassis to this
header according to the pin assignments below. Note the positive and negative pins before
connecting the cables.
PWRBTN (Power Switch):
Connect to the power switch on the chassis front panel. You may configure the way to turn

LED is off when the system is in S3/S4 sleep state or powered off (S5).
HDLED (Hard Drive Activity LED):
Connect to the hard drive activity LED on the chassis front panel. The LED is on when the
hard drive is reading or writing data.
The front panel design may differ by chassis. A front panel module mainly consists of
power switch, reset switch, power LED, hard drive activity LED, speaker and etc. When
connecting your chassis front panel module to this header, make sure the wire assignments
and the pin assign-ments are matched correctly.
